How to use cmake to implement the bazel function?

What is Ray Core? — Ray 2.8.0

The C++ Ray API is currently experimental with limited support and it’s not supported on Windows. You can track its development here and report issues on GitHub. Run the following commands to get started:

Install ray with C++ API support and generate a bazel project with the ray command.

pip install "ray[cpp]"
mkdir ray-template && ray cpp --generate-bazel-project-template-to ray-template

BUILD.bazel

# ray
cc_binary(
    name = "example",
    srcs = glob([
        "*.cc",
    ]),
    data = [
        "example.so",
    ],
    linkstatic = True,
    deps = [
        ":ray_api",
    ],
)

cc_binary(
    name = "example.so",
    srcs = glob([
        "*.cc",
    ]),
    linkopts = ["-shared"],
    linkstatic = True,
    deps = [
        ":ray_api",
    ],
)

cc_library(
    name = "ray_api",
    srcs = [
        "thirdparty/lib/libray_api.so",
    ],
    hdrs = glob([
        "thirdparty/include/**/*.h",
        "thirdparty/include/**/*.hpp",
    ]),
    linkopts = ["-Wl,-rpath, ./"],
    strip_include_prefix = "thirdparty/include",
    visibility = ["//visibility:public"],
